your very welcome and thank you for the kind words. Hope your arm heals up fast.

0.030" thickness. I found it at : www.eplastics.com/PRONAT-03X24X47L-S If you get it from there, make sure you get it with one side smooth 👍

thx

I found it west system

West System 105 Epoxy Resin

thanks for the comment. I found the only way to get a wash out contour in the wing core is to use a cnc. Started making a mpcnc primo just for fun :)

I've got so many things to take care of IRL it's hard to get back into it to be honest with you. Probably do a video to rap up the final assembly in a few weeks.

same boat brother. I’m finally working on a new model now after nearly a year since I finished the last one. About to cut some wing cores tomorrow. :). That’s going to be a really nice model when you get her in the air.

@@banko444 thanks. As I said, I'm in no hurry.

it was the first DLG I made! The tail is just glued up into the Vee configuration. That glider is based on the Apogee dlg model.

I go into the wing tip detail in the Wing Core Prep video. ruclips.net/video/GQ39JWvrBgM/видео.html

thx

Me alegra que lo hayas disfrutado y gracias por las amables palabras.

glad you liked and yes, it makes foam cutting easy and precise. 😎👍

Merci pour vos gentils mots, et la colle s'appelle adhésif en spray Super77.

@@amonus-air2160 ah ! Ok It's the same 3m 77 spray 👍

@@freedom2000 yes, and you don't need much

one other thing, if I did this again, I'd put the hinge on the bottom

@@amonus-air2160 is there a reason ? I saw many gliders with ailerons hinge on top and flaps hinge on bottom. Mainly due to increase bottom angle of flaps. But ailerons mostly go to the top when in motion. So hinge on top seems perfect ?

Thanks

the breather bag is nothing more than a folded piece of poly plastic with paper towel attached with tape to the outside. Thanks for the question :)

very welcome and I appreciate your kindness

I use a carbon fiber arrow shaft thats 31" long and 1100 Spine / Inner Diameter: 4.2mm

@@amonus-air2160 Thank you for your reply! Do you also have cad files of the 3D printed connectors? That would make it a lot easier for me to assemble the model.

@@jordycel not sure what you are referring to

I prefer the spar for increased longitudinal strength with minimal weigh gain

Thanks!

thanks. Hope you are doing well.

😎👍

that's awesome 👌 You'll have enough to do a 1.5m dlg if you're into it 😉

Thank you very much

I've never had a leak from the bag ends. It usually will leak a bit around the fitting. I used plumbers putty. :)

Hi. I just used the image of the Devient in the build folder and scaled it up. It has dimensions.

no problem. Just make sure you get one smooth (glossy) side. Directly effects final finish :)

@@amonus-air2160 Thanks and yes, I did.. I had them also cut the sheet into 8" wide strips at 4' long for a total of 9 strips... yeah! BTW, what viewer is to be used for the .DAT files? Thanks again, DJ

I use Notepad++ to open the .dat files. So, you go to Airfoiltools.com and : 1) choice my airfoils 2) add a new airfoil 3) paste in .dat file numbers. 4) open in plotter to input chord length (I usually add a .5mm halo for cutting wire waste) 5) print out the .pdf and use to make your templates :)

@@amonus-air2160 Thanks again for your help on this...

I found the material at a place called "eplastics". Here's a link to the stuff I used. www.eplastics.com/PRONAT-03X24X47L-S

hmmmm. please, I would love to know how you would manipulate 4 independent control surfaces without using 4 independent servos? Also, please note, the tail section has a spring pull system. Have a great day 😀

thanks

wow is good :)

You and me both!

I’m about to cut out my next wing and acquired some high load 60psi xps for it. MUCH more dent resistant than the off the shelf 15psi stuff. Highly recommend it should you do another build after this one. :-). It has to be ordered from a building supply house. But totally worth it.

I bought some higher density foam before by mistake actually. Your correct, it is way more dent resistant. It's also way more heavier. :)

@@amonus-air2160interesting. My cores were only 1.2g more per wing. Exact same wing. Very much worth 2.4 extra grams as I can now skin the wing with .75 oz glass vs the 1.6 oz I used last time. My new wing will actually be lighter and much stronger as a result. 🤷🏼‍♂️

hmmm...interesting. Could you tell me what you bought? I'd like to see the spec. sheet

sounds good! You'll still need some tow that can conform to the leading edge .

Right. I ordered from aliexpress. Delivery late this month.

yep, Aliexpress is my go too. Good prices/ slow shipping lol

Thank you so much!

thank you so much my friend for the compliments. I find a 3D printer so useful to make what ever I need :)

@@amonus-air2160 Which program do you use for editing the glider parts and print them? I just thinking about this construction method (3D printing).

for the design, I use Fusion360. It's free and very powerful. My 3D printer is an old Ender3. It really makes life easier, not just for these parts, but I've made all kind of things such as tools and things around the house. :)

@@amonus-air2160 Wow, it is really nice! I want to try it! Thank you for your answer!

Thx. I was blessed to have her in my life

awesome 👌 glad I could help 😎

so the CF fabric is described as 12k 200g UD Carbon Fiber Fabric Unidirectional cloth. I buy all my CF from Aliexpress as they have the best prices if you don't mind 2-3 weeks shipping. here's a link: www.aliexpress.com/item/1005004353591241.html?src=google&src=google&albch=shopping&acnt=631-313-3945&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=UneMJZVf&gclsrc=aw.ds&&albagn=888888&&ds_e_adid=&ds_e_matchtype=&ds_e_device=c&ds_e_network=x&ds_e_product_group_id=&ds_e_product_id=en1005004353591241&ds_e_product_merchant_id=562123074&ds_e_product_country=CA&ds_e_product_language=en&ds_e_product_channel=online&ds_e_product_store_id=&ds_url_v=2&albcp=19366866438&albag=&isSmbAutoCall=false&needSmbHouyi=false&gad_source=1&gclid=CjwKCAjw59q2BhBOEiwAKc0ijRiQMVEZGrmqL6puuHsrFZ34FrXM4B6ulcZ_RSCLBwzNei9mLzxY2xoCHm4QAvD_BwE

thank you, glad you liked :)

thank you for the kind words..

much appreciated...thank you

good morning. Plastic sheeting is measured in mils. One mil is equal to .001" . So your plastic is roughly .006" thick. The material I use for the wing mylars is .75mm thick (or about .030") and is the thickest I can use comfortably. I've tried allot of plastic for vacuum bagging...lol and I found polypropylene (PPE) is about the best. I got mine from a company called " ePlastics". Thicker material = better finish quality when vacuum bagging. I made my vacuum pump out of and old bar fridge I picked up at a yard sale. I like using it because it is very quiet, and it's wired to a vacuum switch that turns it on if pressure drops. Because I know you'll ask, the vacuum switch is part# F-4200-X30 and the vendor is "Airtrol" airtrolinc.com/f-4200x%20series-vacuum-switch/ I do use a FoodSaver type bag that I picked up on-line. Comes in a wide roll. I found the best seal for the ends of the bag is good ole latex caulking. Thanks for the questions.

thank you for the kind words my friend. I'm just wrapping up another video on control linkages I hope you like :)

sure! At launch, the dlg will climb at a steep angle. Once it reaches it's peak, you want it to kick it's tail up to achieve a level attitude. This "kick" needs maximum down elevator. Hence the mounting on the bottom. :)

Got it. Thank you!

hi. They were sold as binder/report covers. I wish I had bought more cause I haven't seen them since. lol. There nice due to the thickness ( .5mm for tail group) and as all mylars I use for vacuum bagging , I'll use the thickest I can get away with. ( .8mm for the wings) Thanks for the question.

That's awesome! You're on your way to a wing !!! I can't tell you how many hours I spent finding the sweet spot for temp/speed but it's satisfying once you nail it . 👌

yes, paper towels would soak it up, unfortunately too much in my experience. You still want to leave enough resin for a good lamination.

You're most welcome

Welcome!

the airfoil is the SynergyII . Here is a link if you want to see it's development. www.rcgroups.com/forums/showthread.php?2152557-Synergy-II-wing-development

I keep mine at around 4 to 5. That's all dependent on your weight, construction etc...
